A 54-yeаr-оld pаtient with septic shоck secоndаry to SARS-CoV-2 pneumonia is intubated for worsening hypoxemia. On hospital day 2, the patient has a PaO₂/FiO₂ ratio of 110 despite increasing FiO₂. Lung compliance is markedly decreased, and chest imaging shows diffuse bilateral infiltrates. The AGACNP initiates a lung-protective ventilation strategy. Over the next 14 days, oxygenation gradually improves, and there are signs of clinical recovery. However, the following week, the patient develops persistently reduced lung compliance and difficulty further weaning from mechanical ventilation due to derangements in gas exchange. Which of the following best explains the pathophysiologic progression observed in this patient?
